Code:

<?
$major_city_info = array();
$major_city_info[0] = 'A';
$major_city_info['A'] = 'B';
$major_city_info[1] = 'C';
$major_city_info['C'] = 'D';
$major_city_info[2] = 'E';
$major_city_info['E'] = 'F';

function print_all_array_backwards($city_array)
{  
  $current_item = end($city_array); //fast-forward to last
  
  if ($current_item)
    print("$current_item<BR>");
  else
    print("There's nothing to print");
  while($current_item = prev($city_array))
    print("$current_item<BR>");
}
print_all_array_backwards($major_city_info);

?>
